CAPSULE-MACHlNE.

SPECIFICATION forming part of Letters Patent No. 297,380, dated April22, 1884.

Application filed May 19, 1883. (No model.)

To all whom it may concern.-

Be it known that I, J AMES H. GLovER, of Detroit, county of W'ayne,State of Michigan, have invented a new and useful Improvement inOapsuleGuttiug Machines; and I de clare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it pertaius to make and use it, referencebeing had to the accompanying drawings, which form a part of thisspecification.

My invention consists in the combinations of devices and applianceshereinafter specified, and more particularly pointedoutin the claims.

In the drawings, Figure 1 represents a plan view of apparatus embodyingmy invention. Fig. 2 is a front elevation of a portion of the Fig. 3 isa perspective view of the cutter-plate. Fig. 4 is a separate view. Fig.5 is a side elevation.

The object of my invention is to provide an improved capsule-cuttingmachine in which the mold-pins are projected through a cutterplate, thepins then being rotated about the inner edge of annular cutters, withwhich the cutter-plate is provided. I accomplish this object as follows:

As illustrated in the drawings, A represents a mold-plate provided withcapsule pins or molds a, secured thereto in any proper manner. A is aframe in which said plate may be secured.

A represents guides in which the frame may operate.

B is the cutter-plate provided with suitable orifices, b. The plate isprovided with annular orifices containing cutters I), Which are eachformed by an annular chamfered or beveled edge projecting inwardlytoward the center of the orifice The cutters of the form mentioned maybe secured to the plate in any desired manner. The plate may be providedwith cutters, as shown in Fig. 4, in which asuitable cushion of rubber,I), or other elastic material, should be located behind the cutter, theplate being recessed to receive the rubber and the cutter, as shown, thecutters being adjustable and removable, and may be held in place in anyproper manner. As thus constructed, each cutter may be removed to besharpened, or be replaced by another whenever desired. I do not,however, limit my self to this method of constructing the cutterplate,as a plate of any proper material may be properly sharpened at theperimeter of the orifices I), or a plate of thin material may be used.

B is the frame in which the cutterplate is secured. I prefer that saidframe should be adj ustably secured to guides B", the construction beingsuch that the cutter-plate may be projected over the pins ofthemold-plate, and also be adjusted so that the edge of the cuttersshall be in contact with the moldpins.

0 represents a crank secured in the frame of the mold-plate and providedwith suitable bearings, as shown at c and c, said cranks provided withsuitable gear-wheels, 0, adapted to mesh with a drive-wheel, D, mountedupon a shaft, (1, and provided with a crank, d, or other means by whichit may be rotated. I prefer that there should be two of these crankssecured in the frame of the mold-plate to give greater steadiness ofoperation, though I contemplate the employment of one or more as comingwithin the scope of my invention.

The operation of the device 'is as follows: hen the pins of themold-plate have been dipped in the gelatine and the capsules formedthereon are ready to be cut, the plate is adjusted into the frame A. Thecutter-plate is then projected over the pins with the capsules formedthereon and adjusted so that the edges of the cutters are in contactwith'the capsules. By rotating the shaft d the motion is communicated tothe cranks, and the pins are caused to rotate about the edges of theannular knives of the cutter-plate. The crankarm may be of any desiredlength to give the mold-pins the desired rotation, and the diam eter ofthe orifices of the cutter-plate may be of any desired-measurement, thelength of the crank-arm and the diameter of the orifices being made tocorrespond, so that at each rotation of the pins they will pass aboutthe perimeter of the cutters.

Any desired means may be employed to reciprocate the cutter-plate uponthe mold-plate and for adjusting the cutting-edges against the capsules;also, any suitable mechanism may be employed to give the desiredrotation to the pins about the cutting-edges.

It is evident, in this construction, that the mold-pins are notseparately rotated in the mold-plate, but that the whole plate, with themold-pins rigidly secured thereto, is given such a motion as will causethe pins to rotate about the cutting-edges of thecuttcr-plate.

I have described the cutter-plate so constructed that it may bereciprocated and adjusted so as to be projected over the moldpins andthe cutting-edges brought into contact with the mold-pins; but it isevident, and I would have it understood as coming within the scope of myinvention, that the mold-plate may be provided with means whereby it maybe reciprocated and adjusted so that the moldpins shall be projectedthrough the orifices of the cutter-plate, and then, instead of giving tothe mold-pins the motion described, the cutter-plate may be given amotion similar to that described in connection with the moldplate, sothat the cutting-edges of the plate shall rotate about the mold-pins.

I would have it expressly understood that I contemplate the cutting offof the capsules by either of these operations, as may be desired. l

I am aware thata capsuleqnachine has been provided with a plate havingorifices or sleeves the edges of which serve to sever capsules formed onmoldpins which are reciprocated in the sockets or sleeves; and such,therefore, I do not wish to be understood as claiming. for my inventiondiffers therefrom in that the cutter-plate has an orifice containing anannular beveled cutting-edge which projects inward toward the center ofthe orifice in such manner that a capsule inserted in the orifice andcaused to travel around the orifice against the inwardprojecting beveledcutting-edge will be severed in a rapid, nice, and effective manner.

What I claim is.

1. Inacapsule-cutting machine, aplate provided with an orifice having anannular cutting-edge, in combination with a frame constructed to receivea mold-plate provided with a capsule-mold pin which is adapted to enterthe cutting-orifice of the plate, and mechanism acting on the frame toimpart a circular motion to the mold-pin within said orifice,substantially as described.

2. In a capsule-cutting machine, a cutterplate constructed with anorifice surrounded by an annular beveled cutting-edge projectinginwardly toward the center of the orifice, substantially as described.

3. In a capsule-cutting machine, a plate having an annular cutting-edge,in combination with a frame constructed to receive a moldplate having amold-pin adapted to enter the cutting-orifice of the plate, a crankconnected with the said frame, and mechanism for rotating the crank toimpartmotion to the moldpin in the cutting-orifice for severing thecapsule, substantially as described.

4. In a capsule-cutting machine, a plate provided with an orifice havinga yielding cuttingedge, in combination with a moldplate having amold-pin adapted to'enter said cutting-orifice, and means for impartingmotion to the mold-pin in the orifice, substantially as described.

5. In a capsulecutting machine, a plate provided with one or moreorifices, annular cutters arranged around said orifice or orifices, anda bushing of elastic material around the periphery of the cutters, andmeans for rotating the plate, substantially as described.

6. The combination, in a capsule-cutting machine, of ring-cutterscutting upon their inner peripheries, and a bushing of elastic material,substantially as described.

In testimony \vh ereof I sign this specification in the presence of twowitnesses.
